Watch Idol Ruben Studdard's Shocking Biggest Loser Elimination

On Tuesday's The Biggest Loser, fan-favorite Ruben Studdard was eliminated from the reality weight-loss show. Unfortunately, during his weigh-in this week, it turned out he only lost 5 pounds, not the 11 that his team needed to stay safe. "I worked really, really hard this week," he said. "I swam extra. I walked extra." Unfortunately, the American Idol champ's efforts weren't enough, and he had to bid adieu to the ranch.
